Activity in Response to Fentanyl.

Mean + SEM horizontal activity in centimeters. Activity for C6J mice is shown on the left, and A/J activity data is shown on the right. Data from females is shown in yellow histograms and males are in blue histograms. The first test day mice received either fentanyl (stripped histograms) or saline (solid histograms) and activity was recorded in the open field (OF). On the third day all mice received saline prior to the OF test. *Significant main effect of strain, p<0.00001. **Significantly more activity than any other group or test day, p<0.00001. Total test time was 20-min. cm=centimeters. n=8 per group.
